What damn dirty rednecks and stupid hillbillys have none of. You see "book learn'in" is something you learn by actually picking up a book and being able to read it and comprehend what those letters mean. Since most rednecks and hilbillys are as dumb as a box of rocks, they can't read and think people who can read are the devil. This term is very common in the south, to hear the term used down south, either ask the dude with three teeth fucking a goat or the girl who just blew her brothers.
